Wi-Fi is a type of wireless technology that uses radio waves to provide connectivity to a wired network or the Internet. At home, the office, or a cafe, Wi-Fi is responsible for providing connectivity to our wireless devices. This is a type of technology that many take for granted. This post is intended to help ...

We use encryption for a lot of things...a LOT. For example, we use encryption to protect our web traffic, file transfers, emails, and data storage. It plays a big role in cybersecurity; it's what provides us the data confidentiality we need. Below is a helpful table that summarizes the encryption algorithms required to know for ...

In this blog post, I'll discuss the design and operation of a 4G LTE network. In hindsight, I realize topics such as these can get extremely lengthy. For that reason, I'll limit this discussion down to only the necessary technical details required to understand these new LTE attacks, while excluding any complicating, non-essentials. These new ...

Yesterday, the Wi-Fi Alliance announced the long-awaited, next generation in Wi-Fi security, WPA3. After 15 years, WPA3 will now begin to replace the existing WPA2 protocol, which is currently used by billions of wireless devices every day. For quite some time, WPA2 has long been considered insecure. It has always been vulnerable to brute force ...

A client securely connects to a web server via the TLS 1.2 transport encryption protocol. This is a process that starts with asymmetric cryptography and ends with symmetric cryptography. As a refresher, recall that asymmetric cryptography uses a public and private key pair, whereas symmetric cryptography uses only one shared key. I published a blog ...
